Dry Stack Tailings: An Alternative to Conventional Tailings
Dewatered tailings can still contain 10 20 moisture but the material behaves more like a solid making it possible to dry stack the tailings in containment areas. After being placed in the containment areas the lowmoisture tailings are very stable significantly reducing safety and environmental risks.

Stacking up the benefits Mining Magazine
Dry stacked tailings now large scale. It is widely agreed that DST is the most sustainable route for eliminating the environmental risk of tailings dam failures while at the same time enabling the mining industry to continue even in waterscarce areas by enabling a recirculation of the process water with a minimum of water intake.
Tailings.info Dry Stacking of tailings
Dry stack facilities are also easier to close and rehabilitate require a smaller footprint compared to other surface tailings storage options i.e. higher density can be utilised in aggressive environments e.g. undulating and steep terrain and generate better regulator and public perceptions of tailings storage Davies and Rice 2001 .
Filtered Dry Stacked Tailings The Fundamentals
discussed later. The tailings are then transported by conveyor or truck and then placed spread and compacted to form an unsaturated dense and stable tailings stack often termed a quotdry stackquot requiring no dam for retention with no associated tailings pond. The filtered tailings are not dry b ut
Forward Thinking: DryStack Tailings Designing Processes to
Other environmental safety and economic advantages of drystack tailings include: Reducing the need to extract water from local sources by recycling the water removed from tailings Easier and safer construction of the tailings dam due to lower dam height and the fact that the dam is not holding back liquid or slurry
Dry Stack Tailings Management TAKRAF GmbH
Dry Stack Tailings DST systems are particularly suited to mining operations operating in areas where water conservation is critical they also provide significant safety and other environmental benefits too. Water is life. The worlds water is becoming increasingly poorer in quality and a new approach to the manner in which we plan
Dry Stack Tailings Facility DSTF Expansion Detailed Design
The Dry Stack Tailings Facility DSTF at the Pogo mine consists of an aboveground valley fill waste storage facility in which filtered tailings and development waste rock from the Pogo mine are permanently deposited. The DSTF consists of an outer shell which is constructed progressively in
Dry Stack Tailings Storage Twin Metals
In the dry stack method tailings are placed and compacted in a mound that is concurrently reclaimed with native soil and vegetation. Theres no need for a dam to hold them in place no possibility of dam failure and no longterm storage issues. Whats more due to the deposits geology the tailings will be nonacid generating.
